A slug with a mass of mm = 16 g is shot out of a rifle that has length LL = 0.72 m. The slug spends tt = 0.14 s in the barrel.
a. Calculate the magnitude of the slug's acceleration, in meters per second squared, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion.
b. What is the numerical value of the net force in newtons acting on the slug?
